ACCURACY CHECK
The user is expected to carry out periodic checks of the product's accuracy and general performance.
1) Mount the instrument onto a tripod and set it up 20 m apart from a wall - the X axis showing to the
wall.
2) Switch on the instrument and let the laser complete the self-levelling process.
3) Mark the laser beam on the wall with point „A".
4) Turn the instrument in 90° steps and mark the points „B", „C" and „D" accordlingly.
5) Measure the distance „h" between the highest and lowest point from „A", „B", „C" and „D".
6) If „h" < 2 mm, the accuracy is okay. If the difference is beyond please have the instrument adjusted.
DUAL GRADE APPLICATION
Note
It is recommended to use two receivers.

Laser
Step 1: Let the laser complete the self-levelling procedure.
Step 2: Set the value of the axis with the longest distance. I.e.: X = 1 % / 50 m,
therefore in 50 m = 50 cm.
Now set the value of the Y axis. I.e.: Y = 3 % / 20 m, therefore in 20 m = 60 cm.
